How to Register a Limited Company in Belgium: Legal Steps

The modern names you’ll actually use

Since 2019, Belgium reformed company law under the Companies and Associations Code (CSA/WVV). The old SPRL/BVBA became the SRL/BV (Société à responsabilité limitée / Besloten vennootschap). The SA/NV (Société Anonyme / Naamloze vennootschap) kept its name but its rules were updated. In practice, most startups and SMEs pick the SRL/BV for its flexibility and limited liability; larger or capital-intensive ventures often choose SA/NV.

• SRL/BV: no statutory minimum capital anymore, but you must provide “sufficient initial equity” supported by a 2‑year financial plan. Liability is limited to company assets.
• SA/NV: requires at least €61,500 fully subscribed capital; stricter governance and board rules.

Liability, governance, and who they suit

The SRL/BV is versatile. You can set tight transfer restrictions on shares, appoint one or more directors, and tailor voting rules in the articles of association. For a founder-led business that wants agility — and especially if you plan to bring in investors later — the SRL/BV is usually the sweet spot. The SA/NV shines when you need higher capital, a broader investor base, or a governance model that signals formality to banks and institutional partners.

A quick sketch:

• You’re launching a consulting, tech, or services company with 1–5 founders? SRL/BV.
• You’re raising significant capital or planning a regulated activity (e.g., financial services)? SA/NV, and expect FSMA or sector approvals on top.

Old acronyms still everywhere

You’ll still see SPRL/BVBA in old templates, bank forms, and blogs. Don’t worry: they now map to SRL/BV. When you brief your notary, say “SRL/BV” or “SA/NV” — and confirm the company form explicitly in the deed.

Concretely, the CSA/WVV organizes SRL/BV rules in Book 5 and SA/NV rules in Book 7. Both are federal law, applicable nationwide. If you plan to operate in Brussels, Flanders, or Wallonia, regional permits may still apply on top (e.g., environmental or retail authorisations) — but the company form and incorporation rules stay federal. Fees to get started realistically range from €1,500 to €3,000 including notary and publication.

The notarial deed: your legal birth certificate

To create an SRL/BV or SA/NV, you sign a notarial deed of incorporation. The deed contains your articles of association (name, registered office, object, share capital/equity, governance rules, financial year). For an SRL/BV, you attach a two-year financial plan showing that your starting equity covers the company’s needs. Banks and courts will look at this plan if the company fails early — skimpy plans can backfire.

Costs and timing:

• Notary fees and formalities typically run €1,200–€2,500 (SRL/BV) and a bit higher for SA/NV due to capital formalities.
• Publication in the Moniteur belge/Belgisch Staatsblad adds roughly €250–€300.
• Drafting and signing can take 3–10 working days once you provide inputs.

What you must prepare before signature

Founders provide: identity documents, proof of address, and if a corporate shareholder, corporate documents (extracts, board resolution). For non‑EEA founders, have apostilles/legalisations ready. If you form an SA/NV, proof of €61,500 subscription (and minimum paid‑in amounts) is required; for SRL/BV, evidence of initial equity (cash or in‑kind) and valuation reports for in‑kind contributions. Decide on:

• Directors and their powers (single director or board, representation rules).
• Share classes, transfer restrictions, and any shareholders’ agreement (kept private but aligned with the articles).
• Registered office address in Belgium.

After the deed: quick but critical filings

Within days, the notary files your deed for publication and triggers registration steps. You must also identify ultimate beneficial owners (UBO) and register them in the UBO Register — generally within 30 days of BCE/KBO registration. Missing the UBO deadline can lead to administrative fines under Belgium’s AML law (ranges can be significant). If you’re wondering how to register limited company Belgium legally without delays, start by nailing these early documents — they set the tone for banks, tax, and payroll.

Your enterprise number and the “trade register” everyone means

Belgium no longer uses a classic “Trade Register.” Instead, all businesses are recorded in the Crossroads Bank for Enterprises (KBO/BCE), created by the Law of 16 January 2003. Once registered, you receive a 10‑digit enterprise number — the ID you’ll use on contracts, invoices, and tax filings. The enterprise number later becomes your VAT number once activated (prefixed by BE).

Registration path:

1. Sign the notarial deed.
2. Register via an accredited business one‑stop shop (guichet d’entreprise / ondernemingsloket). They encode your data in KBO/BCE and verify NACE activity codes.
3. Publish the deed and officers in the Moniteur belge (the notary usually handles this).

Costs, timelines, and what to double‑check

• Enterprise counter fee: typically €90–€120 for initial registration (varies by provider and year).
• KBO/BCE assignment: often same day once the counter accepts your file.
• Moniteur publication: generally within 10 working days post‑deed; check that directors, registered office, and object are correctly published.

Double‑check your NACE codes. Pick too narrow a code, and you’ll struggle to add activities later; pick codes unrelated to your real business, and you may draw questions from VAT or sector regulators. Example: a software SRL mistakenly coded as “retail” may be asked why it reports zero stock.

Regional nuances still matter

While KBO/BCE is federal, sector permits can be regional or municipal:

• Brussels: retail, horeca, or environmental permits may go via 1819.brussels or municipal services.
• Flanders: check VLAIO and Omgevingsloket for environmental/urban permits.
• Wallonia: consult SPW Économie/Environnement for activity‑specific authorisations.

Once your enterprise number is active and published, move fast to VAT activation and UBO registration to avoid bottlenecks — essential if you plan to invoice within the first 2–3 weeks.

VAT activation: from number to invoices

Your KBO/BCE number becomes a VAT number once activated with the Federal Public Service Finance. File form e604A (initial VAT identification) — online or via your accountant. The VAT office may request contracts, a lease, website screenshots, or bank details to confirm real activity. Until VAT is active, you legally cannot issue VAT invoices.

Key points and costs:

• Activation typically takes 3–10 working days; plan for longer if you have foreign directors or a virtual office.
• Some founders deposit a bank guarantee when the VAT office deems the profile higher‑risk.
• Using an accountant for setup: expect €200–€600 for VAT onboarding.

Choose your VAT regime and deadlines

• Standard regime: monthly returns and payments by the 20th of the following month.
• Small enterprise scheme: turnover ≤ €25,000 can opt for VAT exemption (no VAT charged, no periodic returns; but you cannot deduct input VAT).
• Quarterly returns are possible below certain turnover thresholds (broadly up to €2.5 million, with exceptions); you’ll make quarterly returns plus possible prepayments.

Don’t forget the EC Sales List (recapitulative statement) for intra‑EU supplies and the Annual client listing due by 31 March for the prior year. Late or missing VAT returns quickly trigger penalties and interest.

Direct taxes and NACE codes

Your company also receives a TIN for corporate income tax. The standard corporate tax rate is 25%; SMEs may benefit from a 20% reduced rate on the first €100,000 of profits if conditions are met. NACE codes chosen at KBO/BCE flow into your VAT profile — if your real activities don’t match the codes, expect questions. If you’re mapping how to register limited company Belgium legally with clean tax onboarding, align NACE, VAT choices, and your first contracts from day one.

Sorting VAT fast avoids frozen cashflow. If you need someone who knows the local VAT desk and what proof they like to see, a Belgian commercial lawyer can coordinate with your accountant. Find yours on NexLaw

What banks look for (and why they sometimes say “no”)

Banks run KYC/AML checks. Expect to provide: deed and publication proof, directors’ IDs, UBO details, a brief business plan, website or deck, and proof of Belgian registered office. Foreign‑owned startups often face extra scrutiny; if your team or clients are mostly abroad, be ready with contracts or letters of intent. Monthly business account fees typically sit between €8–€30, plus card and transfer fees.

Capital and the blocked account myth

Under the CSA/WVV, the SRL/BV no longer has a statutory minimum capital and does not require a blocked capital account. Instead, you must show sufficient initial equity in your financial plan. For an SA/NV, you still need at least €61,500 subscribed capital, with minimum paid‑in rules per share — banks or notaries may hold funds temporarily until the deed is signed. Ask your notary whether to deposit with the notary’s escrow account or a bank certificate; procedures differ.

Timelines, IBAN, and payments abroad

• Account opening: 2–10 working days, longer if the bank’s compliance team escalates.
• International payments: most Belgian banks issue BE‑IBAN and SEPA; for non‑SEPA currencies, add SWIFT options and fees.
• Payment gateways: if you plan to invoice before VAT activation, consider pro forma deposits, but do not issue VAT invoices until activation.

If you want a friction‑free path on how to register limited company Belgium legally, align your bank narrative with your deed and NACE codes. Inconsistencies (e.g., claiming e‑commerce without a website) are a red flag. Where a bank declines, payment institutions or EMIs can bridge the gap — but confirm your clients accept those IBANs.

The moment you hire: registrations on the clock

If your company hires staff, you must register as an employer with the National Social Security Office (ONSS/RSZ). The official guidance sets a tight timeline: register within 5 days of hiring your first employee. Before each employment starts, file a DIMONA (immediate notification) to declare the worker’s start date. Skipping DIMONA risks sanctions that escalate quickly.

Contributions, payroll partners, and mandatory insurances

• Employer social security contributions hover around 25% of gross wages, in addition to gross pay.
• Most companies appoint a payroll social secretariat; expect €100–€200 per employee per month depending on services.
• You must take work accident insurance; premiums vary by sector but often start near a few hundred euros annually.
• Sectoral rules (joint committees) impact minimum wages, overtime, and holiday pay. Pick the correct committee from day one to avoid back pay surprises.

Withholding taxes and documents

Your company withholds payroll tax (précompte professionnel / bedrijfsvoorheffing) and remits it to FPS Finance monthly or quarterly depending on your size. Keep employment contracts, work regulations, and time records tidy; labour inspectors do visit, especially in construction, retail, and horeca.

Hiring your first employee is a big compliance jump. A lawyer can help map your joint committee, register with ONSS, and prepare compliant contracts in FR/NL/EN. If you want a smooth hire without fines, get local help early. Find yours on NexLaw

Corporate income tax and advance payments

Your Belgian company files corporate income tax via Biztax. The standard rate is 25%, with a 20% reduced rate on the first €100,000 for qualifying SMEs. Returns are typically due within 7 months after the financial year‑end (or by the deadline published annually by FPS Finance). Belgium encourages advance payments each quarter; if you pay too little, a surcharge applies (the exact rate is set annually). Accountants usually build a calendar with Q1–Q4 instalments to minimise that surcharge.

Annual accounts at the National Bank (NBB)

Most companies must file annual accounts with the National Bank of Belgium’s Central Balance Sheet Office. Formats vary (micro, small, full), with filing fees often between €70–€300 depending on size and channel. You generally file within 7 months of year‑end and within 30 days of the shareholders’ meeting that approves the accounts. Late filing triggers surcharges that can exceed €100–€1,000 and, for persistent failures, director liability questions.

UBO updates, general meetings, and VAT routine

• Update the UBO Register within 30 days of any change (new shareholder crossing thresholds, director changes affecting control).
• Hold your annual shareholders’ meeting (unless waived under simplified rules for SRL/BV) and document decisions.
• Keep VAT rhythm: monthly or quarterly returns by the 20th, intra‑EU listings, and the annual client listing by 31 March. For e‑commerce, consider OSS/IOSS regimes to simplify EU VAT.

Concretely, plan an annual compliance budget: accounting and filings often run €2,000–€6,000 per year for a small SRL with standard activity. Build these into your pricing from day one — and you’ll avoid the year‑end scramble that sinks many new companies.

How long does it really take?

• Draft + sign notarial deed: 3–10 working days once documents are ready.
• KBO/BCE enterprise number: often same day via the enterprise counter.
• Moniteur publication: up to 10 working days after the deed.
• VAT activation: 3–10 working days (longer for foreign‑owned profiles).
• Business bank account: 2–10 working days, depending on KYC.
• Employer registration (if hiring): within 5 days of first hire; DIMONA before work starts.

What it will cost (typical ranges)

• Notary + publication: €1,400–€2,800 (SRL/BV); SA/NV slightly higher due to capital formalities.
• Enterprise counter (KBO/BCE): €90–€120.
• VAT onboarding via accountant: €200–€600.
• Annual accounting + filings (small SRL): €2,000–€6,000.
• Payroll secretariat (per employee): €100–€200/month, plus employer social charges (~25% of gross).

Your step‑by‑step startup checklist

1. Choose form: SRL/BV for flexibility or SA/NV for capital/governance.
2. Draft articles, 2‑year financial plan (SRL/BV), and gather IDs/authorisations.
3. Sign the notarial deed.
4. Register via enterprise counter to get your KBO/BCE number and NACE codes.
5. Ensure Moniteur belge publication of deed and mandates.
6. File UBO Register data within 30 days.
7. Activate VAT with form e604A; set monthly/quarterly regime.
8. Open a business bank account and align account use with invoices.
9. If hiring: register with ONSS/RSZ, arrange DIMONA, payroll, and accident insurance.
10. Set up accounting, Biztax, and NBB annual accounts filing calendar.

If you’re mapping how to register limited company Belgium legally on a tight deadline, lock the deed date first, pre‑complete KBO/BCE data with your enterprise counter, and have a VAT file ready to submit the moment your enterprise number lands.

Language, translations, and where errors creep in

Belgian deeds and publications run in FR, NL, or DE depending on your registered office. If your governance terms are complex, include an English consolidation for your team — but remember the official language text controls. Foreign corporate shareholders need recent extracts; add apostille/legalisation if required. Mismatched names across documents delay publication and banks.

Addresses, directors, and permits

• Registered office must be in Belgium; virtual offices are acceptable if the activity is compatible, but VAT may scrutinise substance (staff, documents, stock).
• No general rule requires a Belgian‑resident director for SRL/BV or SA/NV, but banks and VAT sometimes look for local “mind and management.” Plan who signs on the ground.
• Certain sectors need prior approval (finance — FSMA/NBB, health, food, retail). Operating without permits risks closure orders and fines.

UBO, KBO, VAT — join the dots

Inconsistencies between the UBO Register, KBO/BCE data, and VAT profile raise red flags. Example: a founder files as “software consultancy” in KBO but applies for VAT as “importer of food” — expect questions or a blocked activation. Keep NACE codes and your first contracts aligned.
